Power Relays, Over 2 Amps

Power relays are electrical components used to control and regulate the flow of electricity in a circuit. With the capacity of carrying a continuous current higher than 2 amperes, a power relay is a heavy-duty device to fulfill the needs of controlling several activities like inflow and outflow of the power. The special power relays with higher capacity are often used in switching high voltages. 8869830000 application field and working principle explores in detail the working principle, application field and the advantages of a power relay.

Working Principle of Power Relays

The working principle of a power relay is quite simple; it functions like a switch, which is controlled by a coil. This coil is de-energized or energized depending on the particular application. The presence of a mechanical contact helps in current or power flow from one side to another. This contact gets opened or closed depending on the flow of the current through the coil.

Usually the output contact of the power relay has a higher voltage than the coil which gives it the advantage to carry higher current. Therefore, this power relay can be used to switch higher voltage or a wide range of circuits. The contacts get activated as soon as the coil gets energized and the contact spring back to its original position when the coil gets de-energized.

Application Field of Power Relays

The application field of a power relay varies depending on the exact purpose of switching. There are many industrial applications in which power relays are used like motorized machines, motor starters and lighting control. Apart from these, there are many domestic applications like lighting appliances, TV sets, and temperature controllers.

Power relays are mainly designed to be cost effective, as well as offer protection to the circuit and its components from erratic operation. In medical equipments, the operation of the power relays should be highly reliable because of the life-saving applications. In industrial applications, power relays must be able to switch higher voltage without any difficulty, where proper isolation is very important.

Advantages of Power Relays

Power relays offer many advantages like time-saving, comfort and cost effectiveness. They are fast-acting and can switch extremely heavy current without any difficulty. Its ability of providing protection from overloading current makes it the best choice for many applications. It can easily handle high voltage and has the capability to switch between high and low voltages.

The compact size and lightweight construction make power relays very capable of integrating into smaller circuits. Another benefit of using a power relay is that it helps in saving energy; as the operation of the relay does not consume energy, it makes sure that the circuit operates with optimal energy efficiency.

Power relays are popular among many electrical engineers and industrial applications. The 8869830000 application field and working principle is a helpful guide to understand the working and advantages of a power relay. With the above brief information, interested engineers can know more about the various application fields and the working principle of power relays.
